Horns with undersize mouths for the application they are used in can exhibit ripple at the bottom end, and increasing the mouth size, or raising the crossover point would be a way to address this, assuming the horn is a good match for the driver with its new mouth, or at the new higher crossover point. Assuming that a rectangular mouth can address this so effectively is a big assumption IMHO, and leaves a bit too much to blind luck (see above post of mine from today). You may like the horn you wind up with, but not necessarily for the logic in your conclusion. To paraphrase WHG*: you can't get a free lunch at midnight even if you pay for it ; )

Time for some "Cowboy Engineering": try it, see what happens. Cardboard and duct tape is good for quick and cheap experimental mid horns, and can tell how the horn loads the driver, and whether it's worth making the design in something more permanent. Let us know how it goes.
